Let's try to discuss the utility of a Java antivirus:
Java virii don't spread autonomously. One has to INSTALL a program and RUN it in order to be infected, and in order for the program to work. As far as i know, a java virus can't be very stealthy, and it can't run automatically on phone startup. (but the folks at Kaspersky Labs sure know it better). Thus, it's hard for a homo SAPIENS to get a Java virus.
So isn't a little thought more important than a piece of software that can't even be implemented in the limited Java Virtual Machine of 'stupidphones'?..
I'll also try to do that 'simple word' explaination for bugirc...
Java programs don't run like ordinary programs, as a part of an operating system. Also, they can NOT launch themselves. When you want to start a Java program, a thing called Virtual Machine is started, and the Java program runs 'inside' it. Thus, you can apply security settings to the VM or to each program, and it can only access limited resources of the device and can NOT alter system data. hope i could explain
